Math Problem Statement

For the graph shown, determine which letter represents the mean, the median, and the mode. Letters may be used more than once.

Solution

The image shows a symmetric bell-shaped curve, which represents a normal distribution. In a normal distribution, the mean, median, and mode are all located at the same point.

In the graph you provided:

  • Point C is the farthest left,
  • Point B is in the middle,
  • Point A is the farthest right.

Since the distribution is symmetric:

  • The mean is at the center (point B).
  • The median is also at the center (point B).
  • The mode is the peak of the distribution, which also lies at the center (point B).

Thus, for this graph:

  • Mean: B
  • Median: B
  • Mode: B

Here are 5 related questions you might find interesting:

  1. What are the properties of a normal distribution?
  2. How do mean, median, and mode differ in a skewed distribution?
  3. What does the area under the normal distribution curve represent?
  4. How would you find the mean, median, and mode for a skewed distribution?
  5. How can you calculate the standard deviation from a normal distribution graph?

Tip: In a perfectly symmetric distribution, all measures of central tendency (mean, median, and mode) coincide at the same point.
